英文摘要	Long lasting phosphorescence has been observed in oxygen-deficient zinc-boron-germanosilicate glass-ceramics after 254 nm ultraviolet lights irradiation at room temperature. electron spin resonance (esr) spectrum confirms the presence of two paramagnetic centers. and the esr signal shows a synchronized decay process with afterglow intensity after removing the excitation light, suggesting the afterglow is associated with the paramagnetic centers which are generated during the irradiation. based on the approximate t(-1) decay law of the phosphorescence intensity, the long lasting phosphorescence is attributed to thermal assisted tunneling recombination between pairs of distant electrons and ge-related oxygen-deficient centers. crown copyright (c) 2010 published by elsevier b.v. all rights reserved.
